Nakano was fighting that Astral Being, whereas we continued to support and protect her from. Not a single one of her shots were aimed at Astral Being. We can't even help her much either.
Astral Being was so powerful. She flies, hovers here and there, can dodge bullets, can even block Nakano's "Power Guns". This meant that the rifles she and we both used were useless. This didn't work, Nakano had a hard time fighting it off.
"Why? Is that all you're capable of? So weak."
Those words from Astral Being were sure to offend Nakano's abilities. She must have been deliberately trying to get Nakano to give up fighting her, leaving Nakano to give up on her own. That way, Nakano will surrender and realize that her abilities will not be able to compete with Astral Being's abilities.
"I am weak? That's just your guess," Nakano said.
"What do you mean? Are you entertaining yourself?"
"Not..."
"So what?"
